PRESS OR SAD IRON.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed September 6,1906. serial No. 333,519.

To all whom, it may concern:

Be it known that I, JAMES BLAINE REP- LOGLE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Press or Sad Irons, of which thefollowing is a specification.

My invention relates to improvements in press or sad irons, and has especial reference to an iron of the character described in which the heat and pressure necessary for its proper operation may be evolved and ef- One of the objects of my invention is to provide a press iron, which may be used in co-operation with a press buck, (an even plane presenting a smooth surface upon which the fabric is lobe pressed or ironed,) made preferably of para-magnetic material, and to cause the flux of magnetic lines of force therethrough to effect the necessary pressure.

Another. object of my invention is the provision of a means for heating the sad-iron and buck, or eitherof them, by the evolution of an electric current supplied to the sad iron.

Other and further objects and purposes of my invention will become obvious to those persons who are skilled in the art from the drawings and description hereinafter.

In the drawings: Figure 1 is a side elevation, showing a part broken away in section, of my new improved sad-iron. Fig. 2 is a section taken on line 22 of Fig. 1. Fig. 3 is a plan View looking at the bottom of the iron, with the parts broken away, showing the magnetic coil and part of the insulation in position. 4,43, 6 and. 7 are diagrammatic representations of the manner in which the coils of the sad iron may be connected with respect to each other, for producing'different effects. Fig. 8 is a diagram of the binding posts and coils.

In all of the views the same reference characters indicate similar parts.

In its simplest form, and that illustrated, my new and improved sad-iron is in substance an iron-clad electro magnet, having its salient magnetic poles in juxtaposition to or forming a part of the smoothing surface of the iron.

Referring to the specific illustration, the body part 10 is a shell of steel, cast iron or other para-magnetic material, having the external appearance of an ordinary sad-iron.

by means of cap screws 1313, or otherwise,

and WVlliC-l'lCfiP screws, for convenience, may

also pass through the handle 14, to secure the same in relation therewith; the core 12 being of such size and proportion as to leave a recess or channel 15 entirely around it, and or proper shape and size to contain the electro-magnetic coils 16 and 16. The core 12 is flanged at the bottom as shown at 12; A shell or spool, of aluminium, brass or other diainagnetic and heat conducting substance, fits snugly about the core 12, and is provided with a projecting rib, 17 which serves to conduct heat to the core. from the interior of the divided coil or coils of wire, hereinafter to be described, and also to divide the channel, between the shell 10 and the core 12, into two annular chambers. The bottom end 17 of the shell or spool 17, is extended so as to exactly occupy the space between the shell 10 and the flange of the core 12, properly supported by each, the whole presenting a smooth and practically continuous surface on the bottom of the press iron.

After the coils 16 and 16 have been wound upon the spool 17, and placed in position, an insulation such as asbestos, or the like may be wound around the coils or otherwise placed on the exterior surface thereof as indicated at 18, between the said coils and the shell 10. Thecoils 16 and 16 are connected to terminal binding posts, such as 16, 16', which are shown connected to the coils 16 by means of the wires 16 and 16 respectively. Coil 16 has its terminals likewise connected to similar binding posts 16 and 16 In winding the coils on the core it is treated so as to prevent contact of contiguous turns, or suitable insulating material such as lnicanite or the like, may be-placed between the contiguous turns, or layers of wire for this purpose, or each strand of wire may be separately insulated. Any method, by which the coils or the separate turns may be sufficiently insulated to prevent short circniting, is sufficient. Preferably the resistance of the coils shall differ somewhat with regard to each other,

and correspondingly the number .of turns may differ, so that the magnetizing effect shall not be equal when the coils are connected in parallel or in series circuit relation to each other. This may be accomplished by varying the size of the wire in the coils with respect to each other or by varying the material of which the wire is composed, or otherwise, as by varying the average length of wire. It being desirable that the magnetizing effect of the two coils, when differentially connected shall not entirely neutralize each other. By this means foul conditions of service are permissible.

When the device as a whole is connected between the terminals of a constant potential circuit and the coils are connected in the manner shown in Diagram 4, that is to say,

- connected in parallel for accumulative magnetic results, they will produce great magnetic strength and correspondingly heavy current consumption,and the density of the current being great the convection of heat due to the current will be correspondingly great. When the coils are connected in parallel, differentially, as shown in Fig. 5, they will produce much less magnetic strength, heavy current consumption and as much heat as in the instance illustrated in Fig. 4. When they are connected in series, cumulatively, as shown in Fig. 6, they will produce medium magnetic strength, minimum current consumption and less heat than in the former instances. When the coils are connected differentially in series, as shown in Fig. 7, they will produce very light magnetic strength and not so mrch current consumption as in Fig. 5, but the heat will be about the same as in the instance illustrated in Fig. 6. In all of the instances illustrated the size of the wire composing the coils shall be so related to the radiating surface of the iron that the electrical energy dissipated in the coil shall be .sufficient to raise the temperature of the iron for pressing requirements.

I have shown the terminals of the coils on the upper surface of the iron and it is apparent that any convenient means, such as a suitable commutator may be employed for the. purpose of conveniently changing the connections as illustrated in Figs. 4, 5. 6 and 7, to produce the results described. It is also desirable that a circuit closing switch shall be located near the handle of the iron for the purpose of closing the electric circuit at the time when the iron is employed, and for opening the circuit at the time when it is not employed, or for opening and closing the circuit at any time that it maybe desirable to'do so. These special features are not subjects matter of my invention, and, therefore, they have not been illustrated or described, as any conventional means for the purpose may be use The arrow heads in the Diagrams 4 to] in--' elusive, indicate the direction of the current through the respective coils when it is flowing in a direction to produce the maximum magnetic result.

In Fig. 2 I have shown, in dotted lines, a phantom illustration of a press buck, which consists, in this case, of a plate or slab of iron or steel, having a smooth upper surface upon which the fabric, or goods, are to be placed in the process ofironing.

It Wlll be apparent that when the coils and spool have been placed within the shell of the iron and the bolts 13-13 have been inserted throu h the upper portion of the shell and into t 1e core 12, that by virtue of the extended surfaces 12 or the core 12, and the corresponding shape of the spool 17, the coils, the spout, the core and the handle will beheld in their respective positions by means of the bolts Iii-13, and that a smooth pressing surface on the bottom of the iron is provided by the parts 1], 12 and 17 It is apparent that if electric current of alternating direction is used, instead of a direct current, that agreat deal of heat will be evolved in the core 12 and the shell 11 by virtue of the hysteresis of the iron, in' addition to that produced by the thermal effect of the current owing to the high current density in the magnetizing coils of the iron. The current-may produce all of the effects tending to augment the heat in the core of the device for the purpose of sufficiently raising the temperature for the requirements of the pressing process.

T e use and operation of my device is as follows: The garment to be pressed is first placed upon the steel or iron buck 20 and the sad-iron, having been heated, by the passage of the current through the coils or by some external means, is placed upon the garment and the magnetizing current passed through the coil, by closing the electric switch which may be placed 'convenient-to the manipulator. The iron-clad magnet, composed of the core 12 and the shell 11, closes its inagcausing a flux of magnetism therethrough, thus producing considerable magnetic attraction between the said iron and the buck, or iron surface, upon which the fabric is laced. When the iron is moved along over the buck it has the effect, by virtue of its heat and the ma netic attraction, to set the fibers of the clothv and this effect is produced in much less time than if the iron were applied without the pressure produced by the magnetic effect thereof.

The magnetic pressure, and also the heat supplied by the effect of the electric current is variable at will by altering the relative direction of the current in the coils in the manner heretofore described. In some instances the magnetic pressure is increased, and coincidently the heat produced by the ICC netic circuit through the iron or steel buck,

. a thin sheet of diamagnetic material so as not coils decreased. In other cases the heat may be increased and the magnetic pressure decreased according to the manner in which coils are connected with respect to each i other and the direction of flow of theelectric current in the electric circuit.

It is apparent that a smooth continuous surface may be made of or placed upon the bottom of the iron, in which case it should be to close the magnet poles of the iron.

For the purpose of illustration I have described a single embodiment of my invention, but it is evident that considerable latitude of variation'may be made therefrom Without departure from the spirit and scope thereof.

Having thus described my invention, what I claim and desire to secure by Letters Pat-- ent, of the United States is:

1. press or sad-iron, the smoothing surface of which is composed in part of both poles of an electro-magnet.
